Dolby Presents 3D Demo

Dolby is showing a technology preview of an encoding and real-time decoding system for frame compatible Full HD 3D. The Dolby system is being developed to use 7.5 Mbps, and is aimed at low bit rate applications such as cable, satellite and online.

Dolby is thinking about a migration path, noting that this would work with current H.264 set top boxes at half res, then could be upgraded at a later date for Full HD.

The Dolby system uses AVC, and it was suggested that for terrestrial broadcasting, it could be put into an MPEG2 transport stream and then would need a suitable decoder. The HPA demonstration showed 1920×1080 24fps content.
